Question

Question: The specific heat of copper metal is 0.385 J/(g° C). How many J of heat are necessary to raise the temperature of a 1.42 kg block of copper from 25.0°Сto 88.5°C? a) 547 J b) 1.37 x 104) c) 3.47 x 104 J d) 34.7 J e) 4.74 x 104 J X​

Answer 1

Answer:

3.47x 10^4

Explanation:

the energy required to raise the temperature is = the mass in grams x the specific heat capacity of copper metal x (final temperature - initial temperature)

1.42 x 10^3 x 0.385 x (88.5-25)= 3.47 x 10^4
